Mosser Lee ML1240 is a set of three measuring tools designed to help you determine the soil moisture, light levels, and pH levels of your plants.

The moisture meter has three zones: red (dry to slightly moist), green (slightly moist to moist), and blue (very moist).

The light meter can measure the amount of light in foot-candles.

The pH meter can measure the pH of your soil on a scale of 0 to 14, with 7 being neutral.

By using these three tools, you can get a better understanding of your plants' needs and how to best care for them.
